[RESEND][PATCH v3 2/6] drm: atmel-hlcdc: avoid initializing cfg with zero

[Claudiu.Beznea]

From: Claudiu Beznea <claudiu.beznea@xxxxxxxxxxxxx>

Remove cfg initialization with zero and read state with
drm_crtc_state_to_atmel_hlcdc_crtc_state() so that cfg to be initialized
with state's output_mode.
